multi-service-debug

Cross-service debugging for Vercel and Cloud Run requires correlating frontend and backend logs using trace IDs. This Skill unifies observability by aggregating logs, generating a distributed trace chain, and pinpointing the failing hop across services.

Distributed tracing tracks a single request across multiple web services using trace IDs. You need it when a failure spans both frontend and backend environments, making it impossible to diagnose the root cause from isolated logs alone.

Root-cause analysis with trace IDs involves chaining log entries from the frontend to the backend to identify the failing hop. This Skill orchestrates that log aggregation and provides structured remediation guidance to resolve the inter-service communication issue.

Yes, diagnosing issues across Vercel and Cloud Run requires access to both frontend and backend logs. You must also provide observed symptoms, affected services, and any available trace IDs to enable accurate log correlation and failure detection.

The best way to correlate logs between Vercel and Cloud Run is by matching trace IDs across both environments. This Skill automates that correlation, enabling end-to-end request tracing and structured remediation steps for inter-service failures.

Requests from Vercel to Cloud Run often fail without frontend errors because the exception occurs in the backend. You need cross-service log analysis with trace IDs to correlate the distributed logs and expose the backend exception causing the frontend failure.
